I know what your thinking add your domain to the /etc/postfix/local-host-names file. If it were only that easy. My problem is that when I try to send email through to local (firstname.lastname@example.org) or remote email address (email@example.com) I get the dredded bounce message. If I re-queue the message, using webmin, I the messages go fine. If I send these emails originally from the server itself, i.e. using webmins webmail or just sending an email from the shell it goes fine.
